Credential.WebhookSecret is optional, and go-playground/webhooks skips signature or token verification when the secret is empty. Anyone who can reach burrito-server's endpoint and knows a tracked repository's URL can forge events to create or delete TerraformPullRequest custom resources with attacker-chosen Branch, Base, and ID fields.

Pairing a real, existing pull request number with an unrelated existing branch in the same repository can therefore cause an unauthorized terraform plan for affected layers using the operator's stored git and cloud credentials.
